The Sum Of Two Numbers Is 61 And Their Difference Is 11

The problem given says that 2 unknown numbers are given, whose sum is equal to 61 and the difference is 11. Let's find the two numbers :

When we add the two numbers :
X + Y = 61

The difference of two numbers :
X - Y = 11

Solution :

If we add the two equations eachother , then we can find the first number.

X + Y = 61
X - Y = 11

2X = 72

Let's divide 72 to 2 for the first number "X" .

X/2 = 36

First number is 36

X + Y = 61
So ;
36 + Y = 61
Y = 61 - 36
Y = 25

Second number is 25
